Hi,

Any help would be greatly appreciated.

Hi Sridevi,

Thank you so much for your fast response. I compared your sample code with my code and realized that the map was not rendering because I was using it inside of a stacklayout. For the page I am designing I need the map to be inside of a stacklayout, so I am just going to have to play around with it a bit more.

Jano

Hi  Jano Moller,

We would like to inform you that you can resolve this problem by setting the HeightRequest and WidthRequest to the SfMap. Since StackLayout height will be infinitive and the map doesn't have a default size.

Code snippet: 

<StackLayout> 

    <maps:SfMaps HeightRequest="500" WidthRequest="500" > 

        <maps:SfMaps.Layers> 

            <maps:ImageryLayer LayerType="OSM"/> 

        </maps:SfMaps.Layers> 

    </maps:SfMaps> 
</StackLayout>  

Let us know if you need any further assistance.

Hi,

The SfMaps control was working well in my app since you provided the code sample. However, it suddenly stopped working again. Could you please look into it, and provide me with a possible solution? That would be greatly appreciated. I am using the latest stable version of the SfMaps control, version 18.4.0.47.

Code sample:

<StackLayout>
        <maps:SfMaps HeightRequest="500" WidthRequest="500" >
            <maps:SfMaps.Layers>
                <maps:ImageryLayer LayerType="OSM"/>
            </maps:SfMaps.Layers>
        </maps:SfMaps>
    </StackLayout>

Hi Jano,

It is looking related to open street map authentication problem and currently we have reported the problem in open street map support forum. Also we are analyzing further on this.

We will update you once the solution found.

Hi Bharathiraja,

Thank you for your quick response. I noticed that OSM was down in the Syncfusion Components for Xamarin.Forms application as well, and decided to switch to the Google Maps API, which has worked well so far as well.
